7 Claims.A (Cl. (iS- 32) This invention relates to improvements in therolls while wringing a heavy wringers, and has for its object to providea never-crush wringer, in which the deformation of a rubber rollcooperates with springs for producing an eiiiciently operating wringer.By the use of a combination consisting of a rubber roll and springs thenecessity for adjustment for diierent thicknesses of garments iseliminated.

In order to provide a suitable cooperation between the rubber roll andthe springs a -spring medium had to be found which would suflicientlydistort the upper or soft roll so as to allow sum-- cient wringing ofthin garments and yet at the same time properly wring heavy garmentswith- 0111;'I stalling the motor or injuring the mecha- A suitablespring for this purpose has been developed which has a compression,ratio between the compression ratios of the .soft rubber roll and a rollformed of a harder rubber, with the result that the soft roll willdeform under lighter pressures and give a sufcient wringing to thingarments, while in the case of heavy garments and an increased pressurethe springs become compressed and allow a heavy wringing to beaccomplished without injury to the mechamsm.

It is also an object of this invention to provide l a simple,eflicentrand attractive wringer 'composed of a base, a top pivotallymounted on the base, and a latch for holding the top securely to thebase, and so constructed that it can be released by a forward orrearward movement of the hand of the operator in engagement with therelease instrumentality. The rolls are locked in operating positionswithout the necessity of any readjustment of the spring tension for therolls.

This release instrumentality secures against accident in the operationof the wringer.

'Ihese and other advantages will appear from the following descriptiontaken in connection with the drawings. j

Figure 9 is an exaggerated diagrammatic view showing the position andconditions of the hard roll, the soft roll and the springs when the maloterials of various thicknesses are introduced be- .tween the lrolls ofthe wringer.

Y a properly `The present wringer'is composed of two essentialsupporting parts, a base and a. top. The base is composed of an end I,an end .2, a front 3 and 15 a rear 4 (Figures l'and 2). The front andrear serve to connect the ends and forma supporting structure for alloperating parts, including the top. The base and the top mounted thereonare f constructed to give a streamline effect so that very limitedopportunity is given for the colleczo tion of dust, dirt and otherforeign material.

In each end there is a pocket 5 '(Figures 5, 6, and 8). Each end hasthereon, around the pocket and at one edge thereof, a U-shaped ange 6which serves to support parts of bearing members. In each pocket thereare two spaced lugs 1, the edges of which are substantially in alignmentwith the edges of the flanges 6. The base carries a lower roll 8, whichis made of harder 3o rubber than an upper cooperating roll and has theusual-shaft 9.

On each end of the shaft 9 is a sleeve II), which is loosely mountedthereon' and forms one part of a bearing member. This' bearing membercom- 35 prises the aforesaid sleeve I0, the exterior bearing ring II,and balls I2 interposed therebetween. The bearing ring II is adapted tobe supported 'in the bottom of the pocket formed between the U-shapedflanges 6 and end walls 2 (Figures 4, 8) and is held against axial orlongitudinal movement therein by the lug's 1; between which lugs 1.andthe flanges 6,v the bearing ring f I nts.

The 'lugs and the flanges prevent any movement` of the sleeve and theballs longitudinally with relation to the shaft.

The end I has therein a hole I3 through which shaped end Il of the shaft9 projects for receiving acoupling I5 (Figure 5). This coupling I5 isused for the purpose of connecting the shaft to transmission mechanismlocated within a transmission housing I6 supported by means of a supportI1 (Figure 1). The transmission housingis connected to the end I bymeans ofl a connection I8 and Vbolts IS. For 55 the purpose of shiftingthe transmission mechanism located within the transmission housing thereis properly supported on the housing a lever 20, which may be used for.connecting the gears within the housing for operating the wringer ineither of two directions.

On top of the base and at the rear thereof, at eachend (Figures 2 and3), is a lug'2i on which the top 22 is pivoted by. means of ears 23 andpivot pins 24 passing through the ears and the lugs. There are two earsfor each lug so that each lug is located between a pair of ears andattached thereto rby a pivot pin 24. Each end of the top is providedwith pockets formed by pocket walls 25, which form partitions betweenthe inner edges of the ears 23 (Figures 5 and 6) In each pocketis abearing housing 26 guided therein by means of a pin 21 extending throughone of the walls 2l into a slot 28 provided in the bearing housing-(Figure 4). At the upper end of the slot 28 is a stop4 29, whichprevents the bearing housing from passing down below a certain point inthe pocket. The vupper edge of each bearing housing is provided with astud lil, which cooperates with a stud 3| located on the top for holdinga spring 32. 'There are two of these springs, one at each end of the`top, which tend to urge the bearing housings lt-downwardly. 'I'hesesprings are so formed that they' have' a compression ratio between thecompression ratio of the harder rubber of the lower 'roll and the softrubber of the upper roll.

Supported within each bearing housing is a' bearing ring, and in thisbearing ringV is a sleeve 34 supported therein and spaced therefrom bymeans of anti-friction balls 35. The sleeve 34 is loosely and rotatablymounted upon one end of a shaft 3B, which forms the shaft of the uppersoft rubber roll 31. At the front of the' base and on each end is yahook Il (Figures 4 and 6). Each hook is adapted to fit between a pair ofears l! forming'part of the top 'and positioned with relation to the topsimilarly tol ears 23 except that the present ears are at the front ofthe top. -f l Each pair of ears l0 carries therein a -releasing andlocking member in the form of a rotor 40. Each rotor intermediate itsends and on opposite sides is cut away to form flat cam v'members 4I forengagement with `the hook I8. At one end of each rotor there is a head42. lI'hese heads are connected by means of a yoke-like handle member4I, each end of which is attached to a head. U nderneath the lower orharder roll the base is formed into two troughlike sections 44 and .45,spaced apart by means of a slot 46. The section 44 is at the front o fthe base, while the section 45 is at the rear thereof. The slot 46 isimmediately beneath the lower roll.

These trough-like parts serve to receive and guide the water from theclothes being wrung (Figures 3 and 6). This water will pass through theslot 46 and isV caught by means of a drainboard 4l, which has at eachend an upwardly extending nange 48 pivoted by means of 'screws 49 to abracketv 50 formed on the base.

When the top and the base are positioned for operating purpos theyassume the position 'shown in' 'Figure 4. In this figure the cam members4I so engage the hooks 38 that the top is held in a fixed relation tothe base. In the event that the hand of thev operator should becomeh ventangled with the clothes or caught between ing with said flanges tohold said bearing 'rings the rolls the handle member 4l is pushedrearwardly until the cam members 4i pass beyond the ends of the hooks,thereby releasing the top from the base so that the top may easily moveupwardly. The same results may be obtained s by pulling thehandle memberforwardlyuntil the parts 4| assume substantially a' vertical p0- sition.i 1

After the top has been released from ,the base, no adjustment of thesprings and the rolls is l0 necessary to a subsequent relocking of thetop on the base. The upper or floating rollerl is so supported in thetop that when the top is locked to the base it will take a co-operatingposition with relation to the lower roller without any l5 adjustment. l

Figure 'l shows how the'rolls are deformed during the wringing ofgarments of dierent thicknesses. The numeral Il represents a'thick tionin the soft rubber roll but a less deformation in the harder rubberroll, and does notl interiere with a satisfactory wringing of a smallpiece of goodssuch as a handkerchief I2.

When the word "hard is used to describe' one 25 of therubber rolls it isintended to indicate that this rubberroil is harder than the soft rubberIt will be understood that I desire to com; prehend within my inventionsuch modifications 30 ascome within the scope of my claims.

Having thus fully described my invention, what I claim as new and'desire to secure by Letters Patent, is:
